SLIDE FOR GUNS.

Application filed December 3, 1924. Serial No. 753,602.

(GRANTED UNDER THE ACT OF To all whom it may conccm:

Be it known that I, BRYAN P. Joron, a citizen of the United States, anda resident of Davenport, county of Scott, and State of Iowa, haveinvented an Improvement in Slides for Guns, of which the following is aspecification.

The invention described herein may be used by the Government, or any ofits oflicers or employees in prosecution of work for the Government, orby any other person in the United States, without payment to me of anyroyalty thereon, in accordance with the act of March 3, 1883.

The subject of this invention is a slide for guns.

hen guns provided with slides of relatively great length move on theircradles in recoil, the unequal expansion and contraction of the slidesdue to the lack of uniformity in the physical properties of differentportions thereof results in binding action, deflection of the piece andundue strain on the training mechanism with the consequent necessity ofmore frequent resighting as firing progresses.

The principal object of the present invention is to avoid binding andWarping efiect of a continuous slide by breaking its continuity to forma large number of relatively interrupted elements on which are mounted acontinuous liner of a thickness insufficient to cause distortion of thegun.

To these and other ends, my invention consists in the construction,arrangement, and con'lbination of elements, described hereinafter andpointed out in the claims forming a part of this specification.

A practical embodiment of my invention is illustrated in theaccompanying drawings, wherein:

Fig. 1 is a view in right side elevation of a gun constructed inaccordance with the in vention;

Fig. 2 is an enlarged sectional view on the line 2-2 of Fig. 1; and

Fig. 3 is an enlarged sectional view on the line 33 of Fig. 1,

MARCH 3, 1883; 22 STAT. L. 625.)

Referring to the drawings by numerals of reference:

In carrying out the invention there is shown at 5 the usual barrelsurrounded through a portion of its length by a jacket 6.

Formed on the under side of the jacket and extending the entire lengththereof are disposed flange members 7 which form slides for the gun asit moves on its cradle in recoil and counterrecoil. The continuity ofthe flange members is interrupted by a plurality of regularly spacedslots 8 for the purpose of dissipating the heat from the jacket todecrease the amount and the inequality therein of the expansion andcontraction of the metal depending on the variation in the rapidity offiring the gun.

The foot portions of the flange members 7 are covered by a continuousliner 9 of bronze or other suitable material to constitute a readilyremovable bearing surface. These liners are of insulficient thickness tocause distortion of the gun.

It will be noted that the foot of the right hand flange member 7 isformed with a heel portion 10 to constitute a support for securing aretracting rack 11 as specifically covered in Patent No. 1,424,105,issued to me July 25, 1922.

\Vhile in the foregoing there has been illustrated and described suchcombination and arrangement of elements as constitute the preferredembodiment of my invention, it is nevertheless desired to emphasize thefact that interpretation of the invention should only be conclusive whenmade in the light of the subjoined claims.

I claim:

1. The combination of a barrel, a jacket therefor, flange members formedon and extending the entire length of the jacket to constitute slidesfor the gun, said members provided with a plurality of spaced slots, arelatively thin continuous liner for covering the foot portion of eachof the flange members, one of said members formed with a heel portion,and a retracting rack secured to said portion.

2. A gun barrel, flange members formed on and extending longitudinallythereof to constitute slides for the bers provided with a plurality ofspaced slots and a relatively thin continuous liner for covering thefoot portions of the members.

3. A gun barrel, flange members formed on and extending longitudinallythereof to constitute slides for the gun, said "flange members providedwith a plurality of spaced slots and a relatively thin linerfor'covering the foot portions of the members.
